IMPROVEMENT IN TREATING- .AND ERBSERVL ING- GRAIN IN BULK,-

The Schedule referred to in these Letters Patent making part of the earns 1 t t I 10 0 t y concern. phtlr to produce sulphurous ac1d. These two furn and the sulphurous acid acts as a dc Be it known thatI, CHARLES EPARROTT, of the :city, county, and State of New York, have invented a new Chemical Process of Treating Grain for the purpose of Preserving it and of Restoring its Quality when Damaged; and I do hereby declare that the followingis' a full, clear, and exact description thereof.

There are three principal causes oi loss or deterior ation in stored grain, viz.

First, the devastation caused by vermin, such as msccts of various kinds and rats and mice. Second, 'thentaint; produced, by mustiuess,'smut,

black-rust, fireeblast, blight,&c.

Third, the fermentation to which grain is liable under the influence of heat and dampness.

Theohject of thislinvention is to destroy or arrest theinci'pient action of these causes of loss and deterioration; and to this end, f n

' It consists inblowing through the graim vwhileon' thegranary floor, or contained in a bin, or any suita- -ble rcceptacle,'a mixture of sulphurous acid and-carbonic acid gases. The carbonicacidis destructive to whatever animal life there is or may be in the grain, pdorizerand an antiseptic and impedes fermentation. a lhe process may be conducted in various waysand with various constructions and arrangements of apparatus, but I will describea simple form of apparatus which will serve to illustrate the process, and

which willwork well in practice.

' Contiguous to the granary, bin, or receptacle con'- taining the grain to be treated, 1 arrange a furnace for the combustion of charcoal, to produce carbonic acid, anda separate furnace or oven for burning sulnaces, or this furnace and oven, have no direct cornmunication with each other, but have outlet-pipes communicating with one common aperture in'the tloor of the granary, or in the bottom or lower part of the bin or receptacle containing the grain.

The outlet-pipeqfi'om the furnace or oven containing the sulphurous acid should be of lead.

The a crime above mentioned ma be covered with P v y a wire-gauze distributer, or be in communication 'with perforated orreticulateddistributors arranged within or under the grain to be treated.

'lhedischarge-pipe from a suitably-arranged fan or blowing apparatus is also in communication with the same aperture as the pipes from the charcoal furnace and the sulphur furnace or oven;

The apparatus is setin operation by igniting the charcoal and the sulphur, and setting the fan or blowing apparatus 'iu'n otion. The blower drives the sulphurous acid and carbonic acid alongwith theair which it itself discharges into and among the grain through which the gases are thus caused to circulate for the purpose of destroying or arresting the incipient action of various causes of deterioration.

' What I claim as my invention,land desire to secure by Letters Patent, is+

The treatment of grain with a mixture of carbonic acid and sulphurous acid gases, substantially as and for the purpose herein specified.
